CLINICAL RESEARCH C

Palsy in a Prison Setting
Benoît Tousignant, Abstract
OD MSc MPH FAAO
Assistant Professor Third nerve palsy (TNP) is a neuro-ophthalmic condition that is likely
École d’optométrie, to be encountered by optometrists in various clinical settings. It affects
Université de Montréal extraocular muscles and may impair eyelid and pupil functions to various
degrees. Its aetiology in adults is often linked to compressive lesions of
the central nervous system or to vascular ischemic causes from systemic
disease such as diabetes and hypertension. This case report presents the
management of a TNP in a multidisciplinary Canadian prison setting,
where the patient population is often underserved. Current practices
for neuroimaging cases of TNP in a conventional clinical setting are pre-
sented. The challenges and advantages of management of TNP in a prison
setting are discussed, highlighting the particularities of caring for the vul-
nerable patient population in the prison setting.
